Materials for a Queen Duvet:

• King Top Sheet
• Queen Top Sheet (I found the individual sheets at target feel really great for the money)
• Sewing Machine
• Buttons or Ribbon for closure

Directions

Prewash both sheets
Iron the King size sheet
Fold and iron the top sheet make yourself a pressed line grid so that your tufts end up straight.
Layout the queen sheet on the floor of your work area, this bottom, sheet is your “sizing guide”
Twist and tuft as desired. I alternated, 'more dramatic tufts’ with ‘smaller tufts’ to get the effect I wanted. While tufting you’ll need to watch the size, the top King sheet can’t get smaller than the bottom Queen sheet.
You’ll need to pin your tufts well to ensure they make it through moving, I did this by ‘weaving’ the pin back and forth to keep the twist.
To keep the tufting sizes consistent I used my seam gauge to measure “the depth” of the twist. My “dramatics” were 2” inches and my smaller ones were 1 inch.
Carefully sew your tufts using a denim needle and a short stitch length. I went back and forth several times to ensure it kept it’s twist. At this point your top sheet resembles, Belle’s Yellow Ball gown.

Once your completely tufted it’s time to match up both the top and bottom pieces right sides together. I found the easiest place to do this was on the bed.
Now you’re going to center the king size sheet on top of the Queen sheet, and pin the top and sides together, I used safety pins to make it easier. You will need to ease in the excess fabric into the seam as you go with little pleats.
Since the Queen sheet is already so nicely hemmed, I used my zipper foot to ‘ride’ along the Queen sheets hem to keep it straight.
After ‘riding’ the Queen’s already done hem you’ll have some excess fabric on each side, so I did a rolled hem on my serger so it won’t fray. (If you don’t have a serger you can pinking shear cut your excess).
On your open side on the bottom, you’ll have extra excess, so you’ll need to decide how you want your closure to work then, you’ll hem it as needed.
I still haven’t added a closure to the bottom (want to do a dramatic color but can’t decide which!)  but you could do ribbon ties or buttons easily.
